AMC quietly rebooted Halt and Catch Fire two days early, slipping into Sunday night’s lineup the first half of the 1980s-set drama’s two-hour Season 3 premiere.

Viewers got their first taste of the new season on Sunday at 11/10c (following the midseason return of Talking Dead, which was conspicuously scheduled to run two hours). AMC corporate communications SVP Jim Maiella confirmed the move on Twitter:

Halt and Catch Fire’s Season 3 opener will officially premiere, in full, on Tuesday, Aug. 23, at 9/8c; subsequent episodes will air Tuesdays at 10 pm. (The series’ first two seasons of course aired on Sunday nights.)

In the third season, which picks up in March 1986, Mutiny leaves Texas for the big leagues of Silicon Valley. Founders Cameron Howe and Donna Clark search for the idea that will launch Mutiny as a player, but new collaborators test their partnership. Gordon struggles to find a place within his wife’s company as Joe McMillan builds upon his empire, reinventing himself with a bold play that shocks the Valley and sends him back into the lives of his old partners.

The low-rated-yet-critically-adored series was renewed in October after a much-buzzed-about second season.
